structure in Python

[Alberto Vera]

Hello:
I have the next structure:
[key1,value1,value2]

['A',1,5]
['B',6,7]

How Can I make it using Python?

How Can I update the value of 6?
How Can I insert a key called "C" and its values?
How Can I delete a key called "B"?
How Can I search a key called "A"(parameter) and get its values?

Regards
